we are talking about sleep and frozen slush and high winds that are making driving dangerous and knocking out power to hundreds of homes. days ago it was 75, while it will not be above freezing at all this weekend. in oklahoma, crews work to clear highways that are snow packed and dangerous and they are open being kitsch yechbs and warming s -- opening kitchens and watching centers across the state. it's 20 degrees colder than normal, the sun has gone down, that's my worst part of covering weather. how long does this cold snap last? >> reporter: we still have another rond of potential ice expected. we had the marathon cancelled

today. yesterday around noon or so they started getting not only the cold arctic air, temperatures feeling not on in the single deng it's but the icy, slick conditions and still people came into town. listen to what they had to endure to get here. >> it took us nine hours, which is normally a four-to-five hour trip, windshield wipers icing up, lines down over the road on the highway, it was closed for a time, went through everything from ice to snow. it was a journey. >> reporter: that was exactly the concern. the threat of freezing rain and people trying to commute into the city and also since there's a second wave this evening, they were worried they'd be trying to leave home in another round of those dangerous conditions on the road. the other concern were the cold temperatures, worried about volunteers being out here for prolonged periods of time.

we keep talking about the temperatures, now cold air. many people without power. 5,000 people lost power yesterday. now it's down to about 500 in memphis. you talk about the temperatures dipping down and the threat that more people can lose power if we continue to see freezing rain tonightthat's what's on everybody's minds right now. >> absolutely. thank you so much. we appreciate you doing yeoman's work out there. a lot of questions also remain after an 85-year-old korean war veteran was mysteriously released after mysteriously being held in north korea for six weeks. merrill newman is now back safe at home. >> reporter: putting on military fatigues in a run-down office in

seoul, former members talk about the korean war. now in their 80s, these men were part of an anti-communist guerrilla group that carried out undercover operations in north korea. they say the released american citizen was one of their leaders. >> translator: newman used to send down orders to us, indicating which island continue to fill trait and occupy. then we used to work on combined operations. >> reporter: looking at photos of newman, the veterans reminisce about their wartime operations. this man worked with newman during the war and said the group is still hated in the north. we accomplished a lot during the war. north korea released a video last weekend newman reading a handwritten apology for killing civilians during the korean war,

an apology that may well have been coerced. a clearly relieved looking newman traveled through beijing on his way home saturday, mentioning nothing of his past. >> i'm very glad to be on my way home. i appreciate the tolerance that dprk government has given for me to be on my way. >> joe biden mentioned a second u.s. citizen still imprisoned in north korea. >> they have mr. bay, who has no reason to be held, should be released immediately and we're going to demand his release as well. >> kenneth bay, a career american missionary has been held in nor korea for over a year, sentenced to 15 years hard labor last may for so-called hostile acts against the regime. bay is currently the longest serving american prisoner in the

north since the korean war. paula hancocks, cnn, seoul. >> survivors of pearl harbor gathered in hawaii for a special ceremony honoring those killed 72 years ago today. the 1941 attack launched america into world war ii. the crowd observed a moment of silence and then a vintage world war ii airplane flew overhead to break the silence. >> president obama defended his six-month nuclear deal with iran today when he spoke at a prominent d.c. forum. the deal requires iran temporarily cap nuclear activities in exchange for slightly relaxed sanctions. critics suggest they are being unrealistic to think they will

give up nuclear capabilities forever. >> one could imagine an ideal world where iran said we'll i dee str -- destroy every element where it's all gone, in which congress passed every one of my bills that i put forward. i mean, there are a lot of things that i can envision that would be wonderful. >> well, the forum is being held by the brookings institution, which is a washington think tank. >> friday's jobs report was a shot in the arm for the fokt and some good news for a white house that hasn't had a lot of it recently. 203,000 jobs were added and one group in particular is kark in. alexandra field tells us who exactly is getting hired. >> deb, young people in particular are reaping the benefits of these better jobs numbers. since the recession, young people have struggled to find and keep jobs in the last month.

we see more of them are collecting paychecks. >> it's a big relief getting a paycheck instead of working for minimum wage. can i actually do stuff now. >> jeff graduated from rutgers university with a degree in engineering. he was underemployed for a year before finding full-time work at flexline. >> we figured there was great potential there and an engineering degree and we grab him. >> young people like delorenzo are reaping the benefits of an committee that's adding jobs. 203,000 jobs were created in november and more of them are in higher paying sectors. >> we saw the predictable but we also saw things like manufacturing, business and

services tend to pay a little built more money. >> reporter: the november jobs report was better than expected. for a third year in a row, more than 2 million jobs have been created. still, that's not enough to make up for the 9 million jobs lost between 2008 and 2009. >> did you think it was going to be difficult to find a job? >> no. i thought i was going to be handed a job. >> in the last year jobs dropped more than a full percentage point and the long-term unemployed are struggling the most. in some places people are fighting for work. walmart opened two stores in washington, d.c. there were 600 job openings and 23,000 job applicants. >> harvard has a higher acceptance rate. >> public perception of the economy may not have quite caught up. only a quarter of people polled said they believe the economy is

getting better. deb? >> alexandra, thanks so much. >> in south africa, ten days of mourning under way for the man many called madiba. also, the nsa, what might they have been peeking into any time? here's a hint it, could have just been in your pocket. that's coming up.

today. in the days ahead, world leaders will travel to south africa to pay their respects. former president george w. bush will fly with president obama to tuesday's memorial. former president bill clinton will also plan to attend. we go live to johannesburg. robin, mandela's funeral will be held on sunday. family, dignitaries, they're all coming together. logistically that is going to be incredible. >> reporter: absolutely. i mean, this really is one of the biggest events we're seeing in recent history. and it's three days into a ten-day mourning period. sunday we're going to see more prayers being wrereconciliation memorials. the south african government is encouraging heads of state to come to this memorial in

johannesburg than it is to get into the small remote town of gunu, the remote island where he will be buried. so all in all quite a busy schedule for south africans. also quite geographically spread out. gives chance for this whole country, people in different areas to be able to join in the memorials and pay their respects to nelson mandela. >> the man who brought south africa into the modern day. robyn, thank you so much. >> there's a statue of mandela in central london where mourners gathered in recent days. senior international correspondent matthew chance spoke with the people there

about mandela's influence and his legacy. >> reporter: we're here in central london, just a few steps from the south african high commission, in the past the scene of vigorous anti-apartheid demonstrations. one tribute says "when i was 3 you kissed me on the cheek and i think you blessed me." and another "to the people of south after cashes thank you for giving the world mandela." there are sentiments like this being expressed all over the world. there are lines of people to sign the book of remembrance. excuse me, sir. what did nelson mandela mean to you? >> nelson mandela to me was just

look christ. >> what do you think that his biggest achievement was? >> i think that he continues to represent hope. i know, our country has got a lot of challenges but he shows the beautiful side of the south african spirit and the heart and the beauty of the south african people, he represents all that good stuff, love, peacefulness, harmony. he he will always represent that for all of us. >> nelson mandela was an icon long before he passed away. over the coming days, especially for those away from south africa, it's a place of pilgrimage. matthew chance, cnn, central london. >> such a humble man, you almost have to wonder what he would be thinking about all of this. >> well, if you got a phone, there's a chance the nsa knows

exactly where you are. that makes a lot of people very uncomfortable, even when they aren't doing anything wrong. as a business owner, i'm constantly putting out fires. so i deserve a small business credit card with amazing rewards. with the spark cash card from capital one, i get 2% cash back on every purchase, every day. i break my back around here. finally someone's recognizing me with unlimited rewards! meetings start at 11, cindy.

well, guess who's keeping tabs on where you're going and where you've been? it's the folks at the nsa. they are tracking locations of

hundreds of millions of devices, in all an astounding 5 billion records a day, according to recent reports. brian todd reports on what they're doing. >> reporter: we've seen cell phones tracked on criminal dr a dramas liked "criminal minds." you can even track your friends on their own cell phone with their permission on a special app. new reports say the national security agency is running a massive program to track the location of hundreds of millions of cell phones around the world. the nsa collects nearly 5 billion location records a day, almost 58,000 records of call information and other data per expect

second. the nsa does it, the post reports, to find unknown associates of people it's targeting for surveillance. >> let's say they're interested in tracking somebody here by the red dot. as that person moves around a path, a certain number of people are going to be following the same general direction. as they move, fewer and fewer people are going down the same exact path. and say fewer people are there and by the time they get to one other location, there's only one person who has been travelng the same path, the green dot right there. >> and they can track when two people arrive at the same location from different directions more than once. cell phones are always emitting location signals, even when you're not making calls and even when your phone is not turned on. senior officials say the phone locations are focused on overseas.

a privacy advocate calls this an intrusive dragnet. >> location data reveals some of the most personal and private aspects of our lives. if we go to an abortion clinic or to an aa meeting, location data captures that, even if we're not telling anyone we're going to those meetings. railroad the nsa would not comment on the post report. it says the program operates so a minimum amount of cell phone location data is not count up in this and that it is -- >> here to talk about this from the civil liberties union and also principal from willow dale

services. gentlemen, is this fair game? if u.s. intelligence wasn't using something as basic as digital tracking, wouldn't we say that the government is negligent? >> absolutely. i'd have to say the technology is so pervasive and so precise, it really must be used to our advantage and clearly the nsa is working within parameters that have been prescribed legally. we have the fisa court that allows to us do that. so the united states is taking advantage of some technologies and capabilities to really do the very, very best it can in terms of tracking those that have -- that the united states has great interest on and known terrorists. and as a result of that, absolutely some innocents will be caught up in this. but because of the nature of the technology and the direction that we want to take this, those innocents, much like brian todd described, will be sifted away

and swept away and not used in any type of ongoing tore developing investigation and/or operation. >> so, christopher with the aclu, let me ask you this, do you see any value to this kind of surveillance or do you think it's run amuck? >> this is not a surveillance program targeted at people suspected of doing something wrong. this is getting vast achlts of data from people who have done nothing to warrant this kind of surveillance. this is nas casting a massive wide net and filtering things out later after the fact, all of this sensitive data is sitting in a government center data. >> part of tracking a bad actor is knowing who they're collaborating with potentially. doesn't this kind of program do something like this?

>> this program violates the privacy of hundreds of millions of people in order to find a few people that the government is interested in. it's simply guilt by. >> all right. we're going to be coming back to this topic. general, we're going to get to you in a minute. but right now we're going to be thinking about whether the nsa has other tricks up its sleeve. we'll ask our guests their take on more of this. stay with us, we'll be back right on the other side. [ woman ] ring. ring. progresso. i just served my mother-in-law your chicken noodle soup but she loved it so much... i told her it was homemade. everyone tells a little white lie now and then.

these days more technology means more ways to spy on all of us. congress doesn't seem eager to outlaw surveillance by the nsa.

general spider marks, before we went to the break, christopher said a lot of innocents are being swept up on this. we're not seeing people be arrested randomly. does he overstate the case, general? >> the fact of the matter is the technology -- the cell phone technology and the nsa's ability to grab the signals and interrogate the signals is so incredibly advanced that there a number of folks that certainly will be swept up, but they will also, because of their activities, if it's totally benign and not characteristic or associated with one of the bad actors will be sifted out because of that. it's not a stretch to say it is intrusive because it is but there is also a methodology to assure innocents remain in that

category of innocent. >> is this a question of the nsa having more oversight, better opportunity or is this the type of program you feel needs to be stopped all together? because congress hasn't moved to do that yet. >> we learned this week this is not being overseen, it's something the executive branch is doing by itself when its partners in forng intelligence services. location data is so sensitive, it reveals where you dleep, when you're at a gun store, at a gay information for a data set for people who are wrapped up into it are not wrapped into it.

>> i agree that we have a certain expectation of privacy, but if this program can save even one life or prevent another 9/11, is it worth it? do you see any worth in it, christopher? >> it would certainly make life a lot easier for the government if they could just search every house that they came across that our founding fathers decided the fourth amendment would be a good idea that, the police should have to go and demonstrate probable cause before they go and search someone's home, this is a dragnet surveillance program that is not overseen by any independent judge or magistrate. it is surveillance gone too far. >> don't you think, general marsh, there should be more accountability and more oversight because right now there is none? >> reporter: i do believe over the mechanisms for oversight certainly are in place. so we could turn a switch and

say let's have some greater transparency in terms of what we're doing, but i think the real conundrum is that the definition of privacy needs to be relooked. every time we pick up any one of our digital devices, that interaction, our interaction, it exists in perpetuity. that could save lives and give the united states security a foot up. >> gentlemen, we could talk for hours on this. i'm fascinated by this entire topic. i was speaking to one of our correspondents earlier, now on our cell phone, you walk into a store, the store will push something on your iphone so people nowhere you are and what you're doing.

just days after the white house had to reverse course anding a knowledge that president obama did in fact know that his uncle lives in boston, his uncle who was cited for dui and had it fight deportation, the president is fighting more criticism of his management style. they say the president rarely, if ever, had a private meeting with katherine sebelius. she took responsibility for the obama care snafus. the white house has not said how many times sebelius did sit down face-to-face with the president. earlier i asked how this report reflects on the white house, the president and his management style. >> i was surprised this week when the president told chris

matthews in an interview that he really didn't think he had to reflect upon his management style, everything was fine in the white house, the real problem was the fact that we have such large signatuagencies government, big bureaucracies, it's hard to get things down. he's the chief executive. he's had five years to address that issue if that's what he thinks. if he thinks a bureaucracy is a problem like this, why did he assign the health care issue to them? i think this president has many good assets, i think there are many good things about him but the management team does have left i think especially in recent times left much to be desired. >> and julian, do you have see this as a leadership issue? >> yes. it could be a defining part of his presidency. jimmy cart ser remembered for

bad management and that could happen tore him. -- to him. if they fix this, i don't think this is what we're going to be talking about. if he doesn't, this could be one of the issues we think about when we think about president obama. >> the white house yesterday called a report about obama's meetings with sebelius misleading andist based on a "false premise." >> texas, oklahoma, arkansas, if you haven't heard yet, it is freezing maybe. that will stay with us. jim,

a man who doesn't stand still. but jim has afib, atrial fibrillation -- an irregular heartbeat, not caused by a heart valve problem. that puts jim at a greater risk of stroke. for years, jim's medicine tied him to a monthly trip to the clinic to get his blood tested. but now, with once-a-day xarelto®, jim's on the move. jim's doctor recommended xarelto®. like warfarin, xarelto® is proven effective to reduce afib-related stroke risk. but xarelto® is the first and only once-a-day prescription blood thinner for patients with afib not caused by a heart valve problem. that doesn't require routine blood monitoring. so jim's not tied to that monitoring routine. [ gps ] proceed to the designated route. not today. [ male announcer ] for patients currently well managed on warfarin, there is limited information on how xarelto® and warfarin compare in reducing the risk of stroke. xarelto® is just one pill a day taken with the evening meal. plus, with no known dietary restrictions, jim can eat the healthy foods he likes. do not stop taking xarelto®, rivaroxaban,

without talking to the doctor who prescribes it as this may increase the risk of having a stroke. get help right away if you develop any symptoms like bleeding, unusual bruising, or tingling. you may have a higher risk of bleeding if you take xarelto® with aspirin products, nsaids or blood thinners. talk to your doctor before taking xarelto® if you have abnormal bleeding. xarelto® can cause bleeding, which can be serious, and rarely may lead to death. you are likely to bruise more easily on xarelto® and it may take longer for bleeding to stop. tell your doctors you are taking xarelto® before any planned medical or dental procedures. before starting xarelto®, tell your doctor about any conditions such as kidney, liver, or bleeding problems. xarelto® is not for patients with artificial heart valves. jim changed his routine. ask your doctor about xarelto®. once a day xarelto® means no regular blood monitoring -- no known dietary restrictions. for more information and savings options, call 1-888-xarelto or visit goxarelto.com.

temperatures to swing back and for the that dramatically? >> it happens. when you get cold air that's record breaking in the northern plains and upper midwest, it is incredibly cold and ice advisories and wind chill advisories. so certainly it is quite cold. that arctic air is in place, all the moisture coming from the south. here's tomorrow at 11:00 a.m., still right just getting toward washington d.c., snow will start around 11:00 or so. then watch the ice. the ice will be the biggest play maker with this, potentially a quarter of an inch or so. then we'll watch it more north or northeast. this is different. washington d.c., winter storm watch, the only big city with a winter storm watch. the snow starts in the morning with the sleep, then maybe an inch or two of snow, potentially a quarter inch of ice.

biggest ice will be west of washington, the suburbs, philadelphia the snow starts in the afternoon, potentially an inch of snow and sleet and then moving to new york city. but it will all be done tomorrow. monday temperatures will be in the 40s so we'll watch this melt. >> thank you, alexandra. it's always fun to see what the weather will do and what challenges it puts on our day. thanks so much. >> they feel pressure to get into the best colleges. no wonder today's teens are called generation stress. we'll talk about that on the other side. ® score on your monthly statements now, for free! that's nice of you! it's a great way to stay on top of your credit, and make sure things look the way they should. awesomesauce! huh! my twin sister always says that. wait...lisa? julie?! you sound really different on the phone. do i sound pleasant? for once in your life you sound very pleasant.

they're being called generation stress, american teen-agers feeling so much more pressure than their parents did when their parents were young. a survey found 38% of parents found their kids in high school reported experiencing what they described as a lot of stress. cnn's kelly wallace talked with two families to get their opinions on the pressures facing teens today. >> i sometimes push myself to almost the breaking point, and they're always telling me, oh, take a break, you need to relax,

you need to live a little. but i say no. >> reporter: you're preparing for your high school tests, you have your activities, your school work. do you go to sleep at night? >> very often, at least three nights a week, we have to take the books out of her hands to turn the light off to go to sleep. >> reporter: if i said one was not stressed at all and ten was super stressed, where would you place injuries? >> seven. >> for me personally, it's going to going to be a four or all the way up to a ten. >> reporter: what gets you to the ten? >> when you have too many people relying on you, that's when it packs when do you guys know the pressure's too much? >> i think i'm a pretty good natured person, so when i start

to get grouchy, i can tell the pressure's getting to me. >> when i get home, the placement of the jacket on the floor, the book bag. i can tell how everyone's day was. >> sometimes wonder, are we adding to the stress of our kids? >> a lot of times, i will turn to nancy privately and ask if i am being too critical, talking to much and she will give me a 10 0% honest feedback and that's good. >> so, what do you do as a mom to try to who lower that pressure? >> i read an article "the new york times" before i even had children and it was saying that not to tell your kids oh, you're so smart, look at how well you did, but to say wow, that's a really good picture you drew, you must have worked really hard. i think the pressure comes from feeling if you don't do well at something, you're not smart or good enough. >> pressure can either be your motivation or your downfall and

if you really manage to make it your motivation, then you're already making something that's a negative turn into a double positive for you. >> one piece of advice that my dad told me is even the pros make mistakes. kobe bryant, he's one of the best players in the nba, but he'll miss a layup. he's not going make all his shots. >> i tell them if they really want to do something fun, walk the dog. nobody's taking me out right now. >> so, is the pressure too much for teens? joining me to discuss this human behavior yal is expert wendy walsh and wendy, listen, i listened to this and kobe bryant missing a layup, there's, it's not just academics. my friends and i were laughing that we couldn't even get into

the colleges we actually attended with the pressures on kids today. >> it's true. i think parents have so much anxiety because they hear reports of the kids in china doing so great and we've got to catch up with their academic standard, but as a result, they're forgetting to teach their kids about the meaning of life and ways to find happiness. in this great american capitalist society, it seems that the only definition of happiness is to get into a good school and make money. research is very clear. that does not equate to happiness. >> it's fascinating because as i was watching this piece, i realized the mom was a friend of mine from college and she was one of the coolest, most laid back people i met, so it's interesting her kids, is it intragram, electronics, the social, media pressure that's turning these kids into type aa

plus kids. >> let's break it down and not blame parents because i've got a teenage daughter myself who's under so much stress. the first thing, the parent's anxiety. the second thing is the schools. right now, we're at a homework high even though the research does not support the fact more homework means better grades. then you add the piece of technology. so, what happens is more teens today are socializing online than face to face and what they lose in that is of course all the ways to pull in information from their friends they lose intimacy, remember, one of the best ways to shore up against anxiety and depression with good, healthy relationships and they're not developing these peer to peer real world relationships at the right pace they need to. >> yeah, it's tough. it's tough. we've both got kids and we know what it's like. thank you so much.
